Abstract	X-ray computed tomography (CT) scanning technology has been applied to the detection of internal defects in logs for the purpose of obtaining prior information that can be used to arrive at better log sawing decisions. In addition to the recognition of wood internal defects, computed tomography technology can be applied to wood nondestructive testing. In the paper the range of CT number in different wood tomography slices can be calculated in statistic method, and then the parameters of CT window level and window width in wood testing procedure are set to get good visual image. Wood density, which has close relationship with other properties in the wood, is vital in wood physical properties testing. The regression curve between CT number and wood density is modeled. A method for the nondestructive testing based on computed tomography is provided in wood defect and wood density.
